ROBERT A. BROOKS, OF CHICAGO, ILLINOIS.

TOILET-CLOSET.

To all whom it may concern:

Be it known that I, ROBERT A. Bnooxs, a citizen of the United States,and a resident of the city of Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements inToilet- Closets; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to toilet closets and is shown more particularlyas a closet adapted for use for railway cars or steamboats though ofcourse useful elsewhere.

Heretofore closets installed on Pullman cars and the like have in someinstances been provided with a concave pan adapted to extend beneath thewaste outlet of the bowl, and serving, to retain a small amount of watertherein sufficient to afford a water seal and to prevent the inward flowof cold air and dust due to the motion of the train. Such constructionsare sometimes inconvenient and objectionable owingto the failure of thesupply of water which causes the closets soon to become clogged andfilthy because of the pan retaining more or less of the waste.Furthermore such closets have heretofore been so constructed that toinsert or remove the pan from the closet it is necessary to release thecloset from the floor as also is necessary for adjusting the mechanismsfor operating the pan for flushing.

The object of the invention is to provide a strong, cheap, simple andcompact closet of the class described provided with a pan hinged beneathand closing the opening or outlet in the bottom of the bowl and theedges of which extend upwardly somewhat above and inclose said outletfrom the bowl, effectively sealing the same after flushing. It is alsoan object of the invention to so construct and insulate said pan as toprotect the water therein from freezing and to so construct the closetand pan as to enable the pan to be inserted or removed through thebottom of the bowl from above without releasing the closet from thefloor and to provide means for operating said pan to dump the contentsand to afford a thorough flush and also an after fill for the closet.

An important object of the invention is Specification of Letters Patent.

Application filed April 19, 1906.

Patented Oct. 12, 1909.

serial No. 312,631.

to provide a ver f strong cheap, simple, durable and compactconstruction, adapted should the supply of water fail to be quicklyadjusted to permit the waste passage to remain permanently open thusinsuring a gravity discharge from the closet and avoiding fouling thesame.

rlhe invent-ion embraces many other novel features and consists in thematters herein-- after described and more fully pointed out and definedin the appended claims.

In the drawings: Figure 1 is a side elevation of a device embodying myinvention showing the same installed as in a Pullman car. Fig. 2 is asimilar view of the side Opposite that shown in Fig. 1. Fig. 3 is a sideelevation similar to that shown in Fig. 2 but showing a slightlydifferent mechanism for operating the pan. Fig. et is a central verticalsection of a device embodying my invention: Fig. 5 is an enlargedfragmentary section illustrating the support for the pan. Figs. G and 7are fragmentary sections illustrating the construction of the pan. Fig.8 is a fragmentary side elevation of a part of the pan and the mechanismfor operating the same. Fig. 9 is a similar view showing a part of themechanism for operating the pan as shown in Fig. 3. Fig. 10 is a centralvertical section of the spring casing showing the push pin thereininverted. Fig. 11 is an enlarged top plan view of the oprating lever forthe iiushing valve. Fig. 12 is a top plan view of the closet bowlshowing the pan in dotted lines. Fig. 13 is a section taken on line13-13 of Fig. L1. Fig. 14 is a section taken on line 14-14 of Fig. 13.Fig. 15 is a section taken on line 15-15 of Fig. 13. Fig. 16 is anenlarged fragmentary detail section showing one of the attaching studsin elevation. Fig. 17 is a top plan view of one of the attaching studs.

A s shown in the drawings: The closet constructed of any suitablematerial, comprises the bowl A which is of the gravity discharge typeand is provided centrally in its bottom as shown in Fig. 12 with arelatively large elliptical soil opening which has its major axislongitudinally of the bowl, and the integrally connected outer wall orcasing of the closet indicated by A. Said outer casing or wall tapersdownwardlyto the base c', which is flanged for attachment to the flooras is usual and through which and in vertical alinement with the soilopening in the bottom of the bowl, isA the waste or soil outlet a2. Thisis continued downwardly below the base flange a, as indicated by a3. Asshown also the usual annular groove (6*, is adapted to receive a gasketwhich is provided around the outlet and within the base flange to insurea tight joint. Said closet is extended rearwardly at the top of thebowl, as indicated by A2 to afford means for attaching the seat andcover thereto and as shown'is provided with a rounded or inturned edgea5 at the top of the bowl within which is provided a water passage a6,opening into the bowl through closely arranged apertures so t-hat theiushing fluid is directed from the periphery of the bowl toward itscentral waste outlet from all parts thereof. lVithin the walls A, of thecloset and integrally connected therewith and with the outer side of thebowl A, is an integral inwardly directed Hoor or wall al, which affordsa small closed compartment, at the front side of the bowl thoughobviously it may be otherwise situated if preferred. Said compart-mentis connected with the waterway a, at the top of the bowl and receives apart of each flushing discharge through the passage as opening thereintoand which it delivers more slowly through a restricted passage orpassages a9, into the bowl at the conclusion of the flush.

An aperture is provided through the walls of the closet on oppositesides thereon and a little at the rear of and above the orifice of thebowl and extended therethrough is a tubular shaft C comprising as showna relatively short section c2, provided on its outer end with a head c3,and screw threaded at its inner end adapted for engagement thereby withthe internally threaded end of of the corresponding but longer tubularshaft section This is externally threaded at its outer end and adaptedto engage thereon a crank arm c, whereby said shaft is partly rotated.As shown the shaft is journaled in suitable bearing sleeves c C, securedin the apertures in the sides of the closet.

Rigidly secured to the shaft C at its center is the concave pan Ccomprising as shown a concave bottom wall 0T which is seamed to orotherwise united with the inner concave bottom 0S affording a relativelylarge air space therebetween, and an inner wall or layer c, of copper orother suitable metal is provided between the same and between which andthe outer wall 0T, is provided a layer of asbestos or othernon-conducting material indicated by C10. Said pan is provided at itsperiphery with an upwardly directed lip c, which acts to extend the sameconsiderably above the orifice of the bowl vwhen in place. rlhe pan isrigidly secured at its rear edge to the tubular shaft indicated as awhole by C, by any suitable connection. As shown said tubular shaft isprovided with lips cl2 and 013 one above the other and which areparallel with each other, and which afford suflicient space between thesame to engage therebetween the rear edge of the pan. A relatively largeaperture is provided through the side of said tubular shaft C and opensinto the air space in the bottom of the pan thus providing means for thecirculation of warm air from the car or room thereinto and preventingfreezing. Said pan as shown in Fig. l2 is oval in shape and is of lesswidth than the length of the opening through the bottom of the bowl andas shown is hinged in such position that when swung upwardly it receivesthe lower downwardly extending edges of the bowl surrounding the openingand extends somewhat above the saine so that when filled with water itforms a water seal for the bowl.

As shown the water or flushing fluid is delivered to the closet througha flushometer of flushing valve D of any suitable construction such forinstance as that set forth in my prior application for flushometer filedDecember l, 1903, Serial No. 183,790 and which as shown is connected atits lower end d, with a suitable source of supply and is connected inone side through a suitable pipe d with the inlet passage of the closet.

As shown one of the side walls of the closet indicated by cl2, is madeconsiderably thicker than the other walls and is cored to provide anupwardly opening relatively broad passage (Z3 which communicates at itstop with the water passage a@ extending around the rim of the bowl. Anaperture is provided through said side wall and extending therethroughis the inlet pipe cl from the flushing valve and indicated by (Z5. Saidinlet pipe is provided on one side with a longitudinal rib or key cfwhich engages in a suitable recess, key way or seat in the closet walland serves to rigidly hold the same from turning.

The inlet pipe is provided with one or more ports opening therethroughinto the water passage Z3 and is closed at its outer end except for avery small waste aperture or passage ZT opening through the end thereofinto the closet. The extremity of said inlet pipe protrudes beyond theend of the wall of the closet and is screw threaded for engagement inthe side of the flushometer and as shown suitable gaskets (ZS, aresecured between the inner end of the pipe and the wall of the closet andthe outer wall thereof and the flushometer to afford a tight joint.

Means are provided for operating the flushometer at the same time or atapproximately the same time that the pan is dumped. For this purpose asshown a lever E is pivoted on the side of the closet and is pivotallyconnected at its rear or longer end with a escale link c, which extendsdownwardly and pivotally engages the arm or crank c whereby the pan isactuated. The front or shorter end c3 of said lever is slottedlongitudinally and engages a pin e2 secured in the stem (Z9 of theflushing valve, so that as the rear end of saidr lever is elevated asshown in dotted lines in Fig. 2 the actuating stem (Z9 of the lushometeris forced down to start the flush and the pan is swung downwardly todump its contents. Means are provided for actuating said lever Eembracing a lever c4, fulcrumed on the wall or other convenient supportadjacent the closet and adapted for manual engagement and connectedatits rear end by means of a rod e5 with the rear end of said lever E.Said connecting rod c5 is provided on its lower end with a spring e,which as shown bears against a stationary stop c7, through which saidconnecting rod passes and its lower end bears on the rear end of thelever E and acts to hold said lever at all times in a horizontalposition and the pan elevated.

If preferred the closet may be emptied and flushed by operating theseat. For this purpose a lever E is pivoted on the side of the closet asbefore described with reference to the lever E and at its shortforwardly directed end e3 is likewise slotted longitudinally and engagesthe pin e2. As shown said stem d10 is lengthened and extends upwardlybeside the seat in position to be manually actuated if desired. At therear end of said lever E as shown is provided a yoke es, in which isengaged a tubular casing Gr within which is a spiral spring g. Saidcasing as shown is closed at the bottom, and at the top by screw caps f/and g2 and through the upper cap is provided a central aperture adaptedto receive a push pin g3, which at its inner end within the casing isprovided with an enlarged head which bears upon said spring and at itsupper end as shown in Fig. 3 bears against a suitable striking plate g?,on the under side of the seat near the hinge. The level' 0G, foractuating the pan is provided at its lower end with a laterally directedpin which engages in a suitable aperture in said casing. Pivotallyconnected Awith the lever E at its rear end is a link G2, which islongitudinally slotted at its upper end and a pin carried on the seatprojects laterally into said slot.

The operation is as follows: The closet is secured in position upon thefloor in any suitable manner and as shown the flushometer is secured inplace by inserting the inlet pipe (Z5, from the inner side of the closetoutwardly and screwing the flushometer and suitable packing onto theprotruding threaded end. rlhe pan is secured in place either before orafter the closet is set. To secure the same in place after setting, thecloset pan is passed downwardly through the aperture in the bottom ofthe bowl and the end of the pipe section c2 is projected inwardly andthreaded into the enlarged head c* of said pipe section The crank isnext threaded onto the outer end of said section c and adjusted andrigidly secured in place by a set screwclt to give the desired positionof the pan when supported to close the bowl. The link c is nextconnected with the lever E, the for ward end of which pivotally engagesthe actuating stem for the flushometer. The connecting rod ci is engagedon the rear end of the actuating lever and the closet is ready for use.

ln flushing actuation of the flushometer by means of the lever et, actsto deliver a sutlicient jet of water through the passage Z3 and theannular passage a, at the top of the bowl which discharges into the bowland pan through the numerous apertures at the top. A considerableportion of the water however passes downwardly into the closed chamberA3 at the front of the bowl, and between the same and the side wall andgradually flows out through the restricted passage a9, after the pan hasbeen returned to position to close the'bowl thus giving an after fill.Obviously any required amount may be delivered into said chamber byproviding' a suflicient number of inlet apertures of suitable sizeleading from the passage o in the rim of the closet. As the flushingbegins the pan has already started to swing downwardly under the actionof the lever E or E and in consequence the pans are thoroughly washedwith the use of a small quantity of water. After the flushing iscomplete the spring e or g or if preferred a spring within theflushometer acts to stop the flow and to carry the forward end of thelever E or E upwardly and the rear end downwardly again returning thepan to position to close the outlet and to receive the flow for theafter ll from said closed chamber. In the construction shown in Fig. 3the flush may be accomplished by pressing the stem clio downwardly withthe hand thereby simultaneously moving` the pan to partly or wholl fopen the outlet or if desired the seat may be lifted when the pin g5engaging the ends of the link elevates the rear end of the lever Emoving the pan downwardly and at the same time actuates the flushingvalve to provide the flush. Vith either of the constructions should thesupply of water fail, the pan may be inimediately adjusted to remain atall times at its lower position or in other words as shown in positionsuch as shown in dotted lines in Figs. 2 and 3, thus having anunobstructed discharge from the bowl. To accomplish this referring firstto Figs. l and 2 the link e is disconnected from the crank c when ofcourse the pan swings downwardly by gravity and is unaffected by theactuation of the .lever et.

In the construction shown in Fig. 10 the .push pin g3 is removed fromthe spring casing G by first removing the cap g2, and the cap is thenreplaced with the push pin inverted in the casing. This permits thespring casing to slide freely upward in the yoke on the lever E as shownin dotted lines in Fig. 3 permitting the pan to swing downwardly.

In the construction described. freezing can never occur under anynatural temperature owing to the fact that the pan is protected on itsbottom the only place at which the same is exposed to the outside air bya double layer of metal and of non-conducting material such as asbestosand is also provided with an interior air chamber which is in opencommunication with the warm air of the car or room through the tubularshaft or pipe C.

Should breakage occur all parts of the closet are accessible and anyrepairs can be effected to the flushing or pan actuating mechanismwithout releasing' the closet from the floor.

For convenience in attaching` the closet to the floor and to permit thesame to be readily detached Awhen desired the base flange is slotted toreceive the attaching studs H. Each of these studs is integrallyconnected at its bottom with an attaching plate 71. drilled andcountersunk to receive screws whereby the same is attached to the floorY, as shown in Fig. 16. Said attaching plates extend inwardly beneaththe Hange which is recessed to receive the same and said studs aresecured in place to correspond with the slots in the closet flange wheninserted over said stud.

Obviously various means may be employed for actuating the pan in unisonwith the flushing means and many details of construction may be variedwithout departing from the principles of my invention.
